Answer:
y =47.5.
Step-by-step explanation:
First eliminate the fractions by multiplying through by the LCM of 7 and 3 which is 21:
21* 6[y-2]/7-21*12 = 21*2[y-7]/3
18(y - 2) - 252 = 14(y - 7)
18y -36 - 252 = 14y - 98
18y - 14y = -98 + 36 + 252
4y = 190
y = 190/4
y = 47.5.
The correct answer is 9.5 feet.
Answer:
LCD = 2(3)(5)(7)(x)(x) is A
LCD = (x - 3)(x + 1) is D
LCD = (x + 2)(x - 3) is C
LCD = 2(3)(5)(7)(x) is B
Answer:
-f(-x) = f(x)
Step-by-step explanation:
Given function is:
f(x)= -2x^5+x^3-7x
To check if a function is even, it is checked that:
f(-x)=f(x)
If f(-x) gives the original function then the function is said to be even.
And if:
-f(-x)=f(x)
which means if –f(-x) gives the original function, then the function is odd. So a function has to satisfy this rule to be an odd function.
Now for the given function:
-f(-x)= -[-2(-x)^5+(-x)^3-7(-x)]
= -[(-2)(-x^5 )+(-x^3 )+7x]
= -( 2x^5- x^3+7x)
Multiplying the negative sign
-f(-x)= -2x^5+x^3-7x
-f(-x)=f(x)
So, the function satisfies this rule to be an odd function. ..
